TANK-HEATER.

Specication of Letters Patent.

Patented June 4L, i918.

Application led April 6, 1917. Serial No. 160,141.

T0 all af/wm t may concermy VBe it known that I, MARTIN E. ANDERSON, a citizen of the United States, residing at De Kalb, in the county of Dekalb and State of Illinois, have invented certain new and useful Improvements in Tank-Heaters, of which the following is a specification.

My invention has reference to tank heaters, of that class of such devices which are designed to be partially submerged in a tank of water used as a supply for live stock.

One of the purposes of this invention is to provide a central hre-retaining chamber having removable parts spaced apart from the outer shell of the heater, so that the water in the tank will at no time be in contact therewith, and in which the heater wall on the outside of the space will have no direct contact with the {ire-box or heat therein.

Another purpose of my invention is to have all of the interior parts of the device arranged and supported in such a way that they can be quickly removed from the heater and replaced therein.

Still another purpose of the invention consists in the provision of parts whereby the character of the lire-box can be quickly changed so as to be suitable for the use of coal or similar fuel,` or for the burning of wood, cobs, or other light material.

Another advantage of my invention consists in conveying the current of heated air in an indirect manne-1', so as to produce a considerable amount of radiation in the lower part of the receptacle, thus warming; the water in the lower part of the tank, producing a more uniform temperature of the water throughout the entire tank.

These and other advantages of my device will more fully appear from the following specification, reference being had to the drawings accompanying the same, in which:

Figure l is a vertical medial section of my invention. Fig. 2 is a similar view with the interior parts removed. Fig. 3 is a similar view showing a modied construction and arrangement of the interior parts thereof. grate 3l.

The main part, or receptacle of my device, is adapted to be constructed of sheet metal. and is preferably, for convenience of construction, formed of two corresponding parts, adaptedto be rigidly fastened to-` gether, The drawings illustrate only one Fig. 4 is a plan view ofthe of these parts, from the inner side thereof, with various supporting devices on the innerface thereof, and a reference to any of such devices will be understood to include a corresponding part on the opposite wall of the receptacle.

My invention comprises a receptacle l, provided with flanges 2, having openings 3 for use with bolts or other fastening means. At its upper part the receptacle has a fuel and draft opening 4 and a flue 5 to which is attached a section of pipe 6, such pipe having an annular groove engaging a bead 8 on the flue, providing a more rigid union of such parts. l/Vithin the pipe (i is a damper 9 of usual construction.

The device is provided with a central fireboX, the rear part of which consists of se`veral sections 10, removably supported by ribs l1 on the-wall of the receptacle l, and provided with overlapping edges whereby a tight -union is formed between the several sections. The ribs 11 are in form of a curve, and conform with the contour of that part of the receptacle 1, a curved passage A being formed betwen such receptacle and the sections 10.

A grate l2 is supported on lugs lf3 on the inner wall of the receptacle, such grate being in substantial alinement with the lower edge of the rear wall of the fire-box, and having at its forward edge a curved lip l upon which is loosely held a partition 15, the upper end of which is normally held against the inner wall of the opening 4C. The upper part of the lire-box has an opening which is normally closed by a plate 1G, hingedly supported by means of trunnions (not shown) on the upper edge thereof engaging hook shaped ribs 17 on the inner wall of the receptacle. The lower edge of the plate 16 is normally supported on a lip 18 of the upper plate l0, and held from upwardmovement by lugs 1Q on the wall of the receptacle. Said plate is capable of being moved upwardly in its support 17 and then dropped downwardly into the position shown in broken lines in Fig. l, permitting `a direct draft from the fire-box to the flue 5.

This feature would ordinarily be made use of when a fire was being started in the fireboX, after which such plate would be closed. For convenience in handling said plate it is provided with an eye 20, readily engaged by a poker or other tool. For the purpose of regulating said draft plate or providing Q incarica said fire-box with fuel, the partition 15 can be tipped forwardly into the position shown in broken lines in Fig. 1, but nothing isiI claimed broadly herein on this lastanentioned feature of the device.

A damper-plate 21 is held on supports 22 in the lower part of the receptacle, and adapted to be tipped forwardly for the pur? pose of removing the ash-pan 23, provided with a bail 24: for convenient manipulation,

The opening l is provided with a cover 25, centrally of which is a hood 2G, having an opening 27 connecting through the hood with an opening 28 in the cover, By this means a current of air can be admitted to the receptacle without exposing the same to the entrance of rain or snow. Hinged in the upper part of the hood is a damper 29 provided with a toothed handle 30 adapted to engage the edge of a slot in the hood. By this means the opening 27 can be fully or partially closed, as desired. When the interior parts of the device are in position, as shown in Fig. 1, and the {irepot therein provided with a supply of fuel under combustion, a current of air passes downwardly through the front part of the receptacle, beneath the fire-box and upwardly through the passage to the flue 5, Such portion of the air as does pass upwardly through the grate 12 is compelled to return downwardly through the same into the passage-way. The radiation is also increased by the curved rear portion ofthe receptacle adjacent to the passage A,

It is obvious that for the purpose of maliing repairs the sections 10 can be readily rcmoved and replaced with other similar secftions. The grate 12, partition 15, plate 16 and damper 21 can also be quickly removed, leaving the interior of the heater entirely clear, as shown in Fig. 2. The device is preferably formed throughout of metal, and can be cheaply constructed of cast-iron,

31 represents an auxiliary grate provided with trunnions 32 which are supported in bearings 33 on the wall of the receptacle 1, the forward end of such grate being held on lugs 31- on such wall. The forward part of the grate 31 is turned upwardly and provided with a concave lip 35 upon which may be supported the partition 15, as shown in Fig. 3. By this means a much larger firebox produced, suitable for the burning of wood or other light material. In this use of the device the upper end of the partition 15 rests upon the wall of the opening 4i, as before, and can be tipped rearwardly for the introduction of fuel.l On the sides of the receptacle 1, in line with the lip 35, are bearings 3G upon which the partition 15 may be supported, if desired. A sufficient space is left between the grate 31 and front wall of the heater for the circulation of the air, and when it `is desired to remove the ashpan, the partition 15 is first lifted out and thc grate 31 tipped upwardly at its forward edge, -into a vertical position. The grate 31 is provided with an eye 37 on its forward edge, by means of which it can be lifted out of the receptacle, when it is desired to discontinue its use.

lVhat l claim as my invention, and desire to secure by Letters Patent of the United States, is: n

1. A device of the .class described, coinprising a receptacle having an air inlet and an air outlet; a central refbox comprising a rear wall, a grate adjacent thereto, and auxiliary grate adapted to be removably supported in said receptaclea and a front wall for said fire-box adapted for use with said first named grate or auxiliary grate,
